SEPARABLE FASTEN ER.

SPEGIFICATION forming part of Letters Patent No. 617,624, dated January10, 1899. Application filed February 17, 1898. Serial No. 670,642. (Nomodel.)

To wZZ whom it may concern.-

Beit known that I, GEORGE E. ADAMs, a citizen of the United States,residing at New Britain, in the county of Hartford and State ofConnecticut, have invented certain new and useful Improvements inseparable Fasteners; and I do hereby declare the following to be a full,clear, and exact description of the same, reference being had to theaccompanying drawings, forming a part of this specification, and to theletters of reference marked thereon.

This invention relates to improvements in socket members of separablefasteners such as are used on garments, gloves, and the like, and hasfor its object to provide a device having but few parts and in which theresilient retaining-arms shall have a large range of flexibility and atthe same timebe protected against breakage by external pressureas,forinstance, as might be brought to bear upon them if stepped upon.

Referring to the accompanying drawings, Figure 1 is a cross-sectionalview through the socket member embodying my present improvement andsecured in place upon the fabric or goods, such as a garment or glove.Fig. 2 is a perspective view of the cap-piece alone. Fig. 3 is aperspective view of the eyelet alone. Fig. 4 is a sectional View throughthese parts, showing them slightly separated, but in line with eachother for attachment to the goods.

Like letters of reference in the several figures indicate the sameparts.

In carrying my invention into practice a cap-piece A, preferably havinga crowning exterior, is formed of sheet metal, with its edge doubledback upon itself at a and this doubled portion turned inwardly to forman annulus or inwardly-extending flange a, the

free edge being then extended in substantially the plane of the outersurface of the cap-piece to a point I), from which point it issubdivided into a series of resilient arms B, which converge upwardlyand have their extremities turned back upon themselves at b. The articleas thus constructed is made up of an integral piece of metal andconstitutes in itself one of the two pieces going to make up the socketmember. The cooperating piece, by

which the socket member is secured in place upon the goods, is made inthe form of an eyelet E, having a base-flange e and a slight1y= flaredfree edge e on the body of the eyelet, which when the parts are broughtinto the relation shown in Fig. 4 and then pressed strongly togetherwill double inwardly and cause the doubled edge of the eyelet to spreadin behind the doubled edge a of the cap-piece,

and thereby firmly and securely unite the parts and grip the web ofgoods between the flanges of the eyelet and said doubled edge of thecap-piece.

The walls E of the eyelet encircle the ends of the resilient arms quiteclosely and preferably limit their outward range of elasticity,although, as is obvious, this is optional with the maker.

The socket member, it will be seen from the above, is composed of buttwo integral pieces, which two pieces in being united secure the socketmember firmly in place upon the goods or garment, and the fasteningprocess consists in a simple application of pressure on opposite sidesof the two members. The parts-4 6., the cap A and eyelet E'are heldtogether very firmly by the cooperating annular edges a and e, the metalof each of which is doubled back on itself.

Having thus described my invention, what 1 claim as new,and desire tosecure by Letters Patent of the United States of America, is

1. As an improved articleof manufacture, a cap-piece for socket membersof resilient fasteners formed with a crowning exterior surface havingits edge doubled back upon itself inwardly and said doubled edge bent into form an inwardly-extendin g annular flange, the free edge being thencarried toward the center of the cap-piece and divided into a series ofresilient arms extending outwardly from the cap-piece and convergingtoward each other to form a resilient holding edge; substantially asdescribed.

I 2. A cap-piece for socket members of separable fasteners formed of anintegral disk of metal having its edge doubled back upon itself inwardlyand said doubled edge turned in to form an inwardly-extending annularflange with a free edge extended toward the center of the cap-piece anddivided into aseries of projecting resilient arms converging toward eachother, combined with an eyelet having a base-flange and a body flaredoutwardly at its edge adapted to take behind the flange on the eyeletfor gripping the goods between it and said doubled flange of thecappiece whereby the holding edges for uniting the two parts of thesocket member are formed 15 by doubled edges of metal; substantially asdescribed.
